TIRE AND TUBE vULCANIzEB..

Specification of Letters Patent.

Patented Aug'. 17, 1920.

Application tiled January 12, 1920. Serial No. 350,770.

`eitizen ot' the United States. residing at Mound Valley, in the countyof Labette and State of Kansas, have invented a certain new and usefulImprovement in Tire and 'lube \"uleanizers, ot' whieh the following is aspeeilieation,

My invention relates t0 improvements in tire and tube vuleanizers.

The objet-t of my invention is to provide a vuleanizer ot the kinddeseribed whieh is simple in eonstruetion, eheap to mannt'aeture, notliable to get ont of order. durable and ellieient in operation. andwhieh may be, readily operated by an inexperienced per- A further objectof my invention is to provide a vuleanizer having means tor regulatingthe heating. as the circumstances may reipiire. and whieli will notexpose the material whieh is being vuleanized to direet eontaet with thesteam employed i'or the heating.

A furtherobjeet ot' my invention is to provide a tire vulea'nizer andtnbe vulranizer, with joint heating means arranged so that tbevnleanizers: may be used eonjointlvv or one at; a time.

My invention provides l'urther novel heating means in the vuleanizer bywhieh a uni form temperature may be obtained and economy in t'uelcombustion.

The novel features ot my invention are hereinafter fully deseribed andeluimed.

The boiler 6 is supported by legs 11 and has loeated below it a suitableburner. sneh as a gas burner 12, which is supplied b v means ot asnpplyfpipe 13 provided with a regulating valve 14 The produets ofcombustion and heated air trom the burner l2 pasa upwardly through thepassage 9 into a eireular ehaniber l5 above the boiler (i, the top olwhieh chamber is the bottom ot the easing 1. smoke pipe 1G is eonneetedto the ehamber 15.

For heating the tire vnleanixing ehamber. there i5 provided in theeasing l a pipe eoil 17; whieh is loeated vertieallv elosely adjaeent tothe inner 'all ot the easing and which has one end eonneeted bv a pipelS with the boiler t3. adjaeent to the upper end thereof. and its; othereml eonneet'ed by a pipe ll) with the boiler l' adiznent to the lowerend thereof.

The lop ot' the easing l may be provided with a tinrnloim-ter1&2. by whieh the interior temperature of the tirey ehainber nlalv beaaiertained, i

ln the tire chamber is mounted `a remov able pel't'oiate basket 131.prel'erzdil-vy baring a bail Qt. tbe basket being adapted to eon tainthe tirear whit-li are to be vntraniwd. lrelerablv the basket Eil resta'upon a bed ot'V aand, 25 disposed npon `the upper side ot' the bottomol` the eaaing l. lrel'erablv the :wbeotos lining It on the bottom ot"the -:Ising l doea` not extend aeross that portion 0l' the bottoniwhit-h ia direetllv above the liv this arrangement` the lit-.tt from theebamber l5 is readily eonllt) ducted throu h the bottom of the casing 1to the sand ed 25, thereby assisting the steam coil 17 and retainingr aneven temperature in the tire heating chamber.

Connected to the top of the coil 17 are a plurality of connecting pipes2G, having with the usual air bags, which are commonly employed toinfiate tubes which are to be vulcanized. Each tube 26 is provided witha shutoff valve 27, which is closed when the tube ismot in use.

For vulcanizingr inner tubes, I provide a rectangular flat hollow box 28of the ordinary type havinor at one end a steam discharge cock 29, fig.2. The' box 28 is supported by a pipe 3U, Fig. 1, which extends throughthe side Wall of the casin 1 and is connected to the steam pipe 18. hepipe 30 also serves to supply steam to the interior of the closed box28.

In the pipe 18 above the pipe 30 is a shutofi' valve 3l, the handle ofwhich extends through the side wall of the casing 1 so as to beaccessible from the exterior of the casing. ihen the Steam box 28 is tobe used, the valve 29 is opened and the valve 31 closed or partlyclosed, according to whether or not the tire chamber is to be usedsimultaneously with the use of the steam box 28. no tires are to becooked, the valve 31 is fully closed.

tires are to be cooked simultaneousl with the use of the steam box 28for v u canizing tubes, the valve 31 may be opened sufficiently topermit of the deslred How of steam through the coil 17, such regulationof the valve 31 being dependent, of course,

valve 33.

In the operation of my invention, when it iS desired to cook tires, thelatter are pro` placed in the basket 23. pipes 26 are then respectivelyconnected with the air bags, not shown, after which the valves 27 areopened.

The tire cooking chamber will be heated b the steam coil 17 and the sandbed 25. The steam from the-coil 17 will distend and heat the air bags inthe tires by means of the connecting pipes 26. Wjien the tires have beenvulcanized, the cover 2 is swung to the open position, the tubes26idisconnected from the air bags, after which the basket 23 with thevulcanized tires therein may be lifted by means of the bail 24 out o1' etire cookin chamber.

When it is esired to vulcanize tubes on the box 28, the valve 31 may beclosed and the valve 29 opened, upon which steam from the pipes 18 and30 entering the box 28 will eat the latter sufiiciently for vulcanizingof the tubes which are mounted on the box 28 in the usual *mannen Awater gage 34 of the ordinary type may be disposed at the exterior ofthe casing 4 and connected to the boiler 6 in the ordinary manner.

I do not limit my invention to the structure shown and described, asmany modifica tions, within the scope of the appended may be madewithout departing from the spirit of my invention. so

1. In a vulcanizer, a tire heating chamber, a casing supporting saidchamber, a boiler located in said casing, means in said casing,r forheating said boiler and said chamber, and a steam pipe connected withsaid boilel and havinp,r a coil located in said chamber.

having an opening in its top and a cover for said opening, a 'steam pipeextending` in 90 and adapted to heat said chamber, a tire containerremovable from 'said chamber through said opening, and a tube connectedto said steam pipe and adapted to be connected with an inflating bagmounted in a tire placed in said container.

3. In a vulcanizer, a tire heatin r chamber aving an openin r and acover t erefor, a steam pipe exten( ing into and adapted to heat saidchamber, means in said chamber for containing tires and holding.;` themout of contact with said steam pipe, and a tube connected with saidsteam pipe and ada ted to be connected with an infating bep,r 1n a tireplaced in said containing means.

4. In a vulcanizer, a tire heating chamber, a boiler located below saidchamber and having a passage therethrough adapted to convey heatedproducts of combustion name to this specification.
